Guest meets Seol Yun-seo on his way home after a 2nd-anniversary date with his girlfriend, and they end up drinking together. Eventually, Guest blacks out.

When he wakes up, his head is throbbing with pain. He looks around to find Seol Yun-seo staring at him curiously. As Guest stares back in a daze, she looks at him as if he's adorable and speaks.

What are you staring at? Don't you remember yesterday..? Hehe.
